UTILITY MODEL CONTENTS

[0005] The utility model aims to provide a cabinet processing wood drying device to solve the problems in the background art.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical scheme:

[0007] A wood drying device for cabinet processing includes a drying chamber. A wood pressurization mechanism and a steam jet mechanism are installed at the top of the drying chamber. An inert gas injection mechanism is installed on one side of the drying chamber. Low-speed fans are fixedly installed on both side walls of the drying chamber. Temperature and humidity sensors are fixedly installed on the side walls of the drying chamber. An oxygen sensor is fixedly installed at the top of the drying chamber. There are at least eight low-speed fans symmetrically installed on both sides of the drying chamber. There are four temperature and humidity sensors symmetrically arranged on both sides of the drying chamber.

[0008] By adopting the above technical solution, the start of a low-speed fan can promote micro-circulation of air inside the drying room and balance the temperature and humidity differences in different areas.

[0009] Preferably, the wood pressing mechanism includes a hydraulic lifting rod, a fixed plate fixedly installed at the bottom end of the hydraulic lifting rod, a strong spring fixedly connected to the bottom end of the fixed plate, a pressure plate fixedly connected to the bottom end of the strong spring, a support frame fixedly installed at the top of the drying chamber, a limit rod fixedly installed at the top of the fixed plate, the top end of the limit rod passing through the support frame and slidably connected to the support frame, a limit end fixedly provided at the top of the limit rod, a telescopic sleeve sleeved on the outside of the strong spring, the telescopic sleeve being a ceramic-coated aluminum alloy sleeve, the strong spring being a nickel-plated stainless steel helical spring, and at least twelve strong springs being provided, evenly distributed between the fixed plate and the pressure plate, the pressure plate being a titanium alloy plate, and having several ventilation holes.

[0010] By adopting the above technical solution: Activating the hydraulic lifting rod causes the fixed plate and pressure plate to move upwards. A limit slide rod is installed at the top of the fixed plate, which slides in conjunction with a support frame fixedly installed at the top of the drying chamber, ensuring the verticality of the fixed plate's movement and guaranteeing stability. Then, the wood to be dried is placed inside the drying chamber, and the hydraulic lifting rod is activated again to move the fixed plate and pressure plate downwards until the pressure plate is pressed firmly against the top surface of the wood. At this point, the spring contracts. During the drying process, utilizing the restoring performance of the strong spring, when the wood shrinks, the strong spring effectively compensates for the shrinkage stress of the wood, maintaining a compressed state and preventing wood deformation.

[0011] Preferably, the steam jetting mechanism includes an electric heating steam generator, a steam supply pipe, a spiral diverter pipe, and a nozzle. The bottom end of the steam supply pipe is connected to the output end of the electric heating steam generator, and its top end extends into the drying chamber. The top end of the steam supply pipe is fixedly connected to the input end of the spiral diverter pipe. The nozzle is fixedly installed at the bottom end of the spiral diverter pipe. An installation ring is fitted on the outside of the spiral diverter pipe. A hanger rod is fixedly installed at the top end of the installation ring. The top end of the hanger rod is fixedly installed at the top of the drying chamber. A perforated plate is fixedly installed at the bottom of the drying chamber. A return air chamber is provided at the bottom of the perforated plate. A return air duct is fixedly installed on one side of the return air chamber. The output end of the return air duct is connected to an external industrial dehumidifier.

[0012] By adopting the above technical solution: by turning on the electric heating steam generator, hot steam enters the spiral distribution pipe through the steam delivery pipe and is sprayed out into the drying room through the nozzle. In conjunction with the return air chamber at the bottom of the drying room, the output end of the return air pipe is connected to an external industrial dehumidifier to achieve the drying effect of wood. Among them, the spiral distribution pipe can cover a larger spray range, so that the steam can be more evenly distributed in the drying room.

[0013] Preferably, the inert gas injection mechanism includes a nitrogen tank, a nitrogen pump is fixedly connected to the output end of the nitrogen tank, an injection pipe is fixedly connected to the output end of the nitrogen pump, the output end of the injection pipe extends into the drying chamber, an oxygen discharge channel is fixedly installed at a diagonal position at the bottom of the drying chamber, and an oxygen discharge valve and an oxygen sensor are installed on the outside of the oxygen discharge channel.

[0014] By adopting the above technical solution: by starting the nitrogen pump, nitrogen is pumped into the drying chamber. At the same time as the nitrogen is injected, the oxygen exhaust valve is opened. Since nitrogen is lighter than oxygen, the heavier oxygen sinks and is discharged through the oxygen exhaust channel. The injection of nitrogen can not only slow down the oxidation rate of organic components in the wood, but also make the wood color less likely to change.

[0015] Preferably, the drying chamber is hinged to a sealed door at one end, the drying chamber is made of double-layer stainless steel, and the middle layer is filled with a ceramic fiber insulation layer. A PLC control panel is fixedly installed on one side of the drying chamber, and the PLC control panel is electrically connected to the hydraulic lifting rod, low-speed fan, temperature and humidity sensor, oxygen sensor and nitrogen pump.

[0016] By adopting the above technical solution, the drying process can be easily controlled by staff through the settings of the PLC control panel.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This cabinet processing wood drying device uses a hydraulic lifting rod in the wood pressing mechanism to move a fixed plate, a strong spring, and a pressure plate up and down to achieve a pressing effect on the top surface of the wood. During the drying process, when the wood shrinks in thickness, the restoring performance of the strong spring effectively replenishes the shrinkage stress of the wood, keeping the pressure plate in a pressing state, preventing wood deformation, and ensuring drying quality.

[0019] 2. This cabinet processing wood drying device, through low-speed fans set on both sides of the drying chamber, can promote micro-circulation of air inside the drying chamber, balance the temperature and humidity differences in different areas, improve the drying uniformity of wood in different layers, and thus further ensure the quality of wood processing.

[0020] 3. This cabinet processing wood drying device, through an inert gas injection mechanism consisting of a nitrogen tank, nitrogen pump, injection pipe, oxygen exhaust channel, oxygen exhaust valve, and oxygen sensor, injects nitrogen into the drying chamber to reduce the oxygen concentration inside the drying chamber. Nitrogen is an inert gas, which not only slows down the oxidation rate of organic components in the wood, making the wood color less prone to change, but also stabilizes the gas environment inside the drying chamber, reducing the risk of fire and explosion.

[0021] 4. This cabinet processing wood drying device, through the setting of a spiral diversion pipe, can cover a larger jet range, so that the steam can be more evenly distributed in the drying room. Attached Figure Description

[0028] Please see Figures 1-4 As shown, this utility model provides a technical solution:

[0029] A wood drying device for cabinet processing includes a drying chamber 1. A wood pressurization mechanism and a steam jet mechanism are installed at the top of the drying chamber 1. An inert gas injection mechanism is installed on one side of the drying chamber 1. Low-speed fans 2 are fixedly installed on both sides of the inner wall of the drying chamber 1. Temperature and humidity sensors 17 are fixedly installed on the inner side wall of the drying chamber 1. An oxygen sensor 16 is fixedly installed at the top of the inner wall of the drying chamber 1. There are at least eight low-speed fans 2, which are symmetrically installed on both sides of the inner wall of the drying chamber 1. There are four temperature and humidity sensors 17, which are symmetrically arranged on both sides of the inner wall of the drying chamber 1.

[0030] The above solution promotes micro-circulation of air inside the drying room 1 by starting the low-speed fan 2, thus balancing the temperature and humidity differences in different areas.

[0032] The above solution involves activating the hydraulic lifting rod 3, which moves the fixed plate 4 and pressure plate 6 upwards. A limiting slide rod is installed at the top of the fixed plate 4, which slides in conjunction with the support frame 18 fixedly installed at the top of the drying chamber 1, ensuring the verticality of the fixed plate 4 and its stability. Then, the wood to be dried is placed inside the drying chamber, and the hydraulic lifting rod 3 is activated again to move the fixed plate 4 and pressure plate 6 downwards until the pressure plate 6 presses firmly against the top surface of the wood. At this point, the spring contracts. During the drying process, the restoring performance of the powerful spring 5 effectively compensates for the shrinkage stress of the wood as its thickness contracts, maintaining a compressed state and preventing deformation.

[0033] In this embodiment, preferably, the steam jetting mechanism includes an electric heating steam generator 7, a steam supply pipe 8, a spiral diverter pipe 9, and a nozzle 10. The bottom end of the steam supply pipe 8 is connected to the output end of the electric heating steam generator 7, and its top end extends into the drying chamber 1. The top end of the steam supply pipe 8 is fixedly connected to the input end of the spiral diverter pipe 9. The nozzle 10 is fixedly installed at the bottom end of the spiral diverter pipe 9. An installation ring 901 is sleeved on the outside of the spiral diverter pipe 9. A hanging rod 902 is fixedly installed at the top end of the installation ring 901. The top end of the hanging rod 902 is fixedly installed at the top of the drying chamber 1. A perforated plate 20 is fixedly installed at the bottom of the drying chamber 1. A return air chamber 21 is provided at the bottom of the perforated plate 20. A return air duct 22 is fixedly installed on one side of the return air chamber 21. The output end of the return air duct 22 is connected to an external industrial dehumidifier.

[0034] The above scheme involves turning on the electric heating steam generator 7, allowing hot steam to enter the spiral diverter pipe 9 through the steam delivery pipe 8, and then being sprayed out into the drying chamber 1 through the nozzle 10. In conjunction with the return air chamber 21 at the bottom of the drying chamber 1, the output end of the return air pipe 22 is connected to an external industrial dehumidifier to achieve the drying effect of wood. The spiral diverter pipe 9 can cover a larger spray range, allowing the steam to be more evenly distributed in the drying chamber 1.

[0035] In this embodiment, preferably, the inert gas injection mechanism includes a nitrogen tank 11, a nitrogen pump 12 is fixedly connected to the output end of the nitrogen tank 11, an injection pipe 13 is fixedly connected to the output end of the nitrogen pump 12, the output end of the injection pipe 13 extends into the interior of the drying chamber 1, an oxygen discharge channel 14 is fixedly installed at a diagonal position at the bottom of the drying chamber 1, and an oxygen discharge valve 15 and an oxygen sensor 16 are installed on the outside of the oxygen discharge channel 14.

[0036] The above scheme involves starting the nitrogen pump 12 to pump nitrogen into the drying chamber 1. At the same time as the nitrogen is injected, the oxygen discharge valve 15 is opened. Since nitrogen is lighter than oxygen, the heavier oxygen sinks and is discharged through the oxygen discharge channel 14. The injection of nitrogen can not only slow down the oxidation rate of organic components in the wood, but also make the wood color less likely to change.

[0037] In this embodiment, preferably, a sealing door 23 is hinged to one end of the drying room 1. The drying room 1 is made of double-layer stainless steel, and the middle layer is filled with a ceramic fiber insulation layer. A PLC control panel 24 is fixedly installed on one side of the drying room 1. The PLC control panel 24 is electrically connected to the hydraulic lifting rod 3, the low-speed fan 2, the temperature and humidity sensor 17, the oxygen sensor 16, and the nitrogen pump 12.

[0038] The above solution allows for convenient control of the drying process by staff through the settings on the PLC control panel 24.

[0039] In this embodiment, a wood drying device for cabinet processing is used by first activating the hydraulic lifting rod 3 via the PLC control panel 24. This causes the lifting rod to move the fixed plate 4 and pressure plate 6 upwards. The top of the fixed plate 4 is equipped with a limit slide rod, which is slidably connected to the support frame 18 fixedly installed at the top of the drying chamber 1, thereby ensuring the verticality of the movement of the fixed plate 4 and ensuring stability during use. Then, the wood to be dried is placed inside the drying chamber, and the hydraulic lifting rod 3 is activated again to move the fixed plate 4 and pressure plate 6 downwards until the pressure plate 6 presses firmly against the top surface of the wood. At this point, the spring contracts, closing the sealing door 23. Then, the valve of nitrogen tank 11 is opened, and nitrogen pump 12 is started via PLC control panel 24, allowing nitrogen to be pumped into the drying chamber 1. Simultaneously, oxygen exhaust valve 15 is opened. Because nitrogen is lighter than oxygen, the heavier oxygen sinks and is discharged through oxygen exhaust channel 14. By observing the data fed back to the PLC control panel 24 from oxygen sensor 16 installed on the outside of oxygen exhaust channel 14, operators can control the nitrogen and oxygen content inside the drying chamber 1 by controlling the start and stop of nitrogen pump 12 and oxygen exhaust valve 15. The injection of nitrogen not only slows down the oxidation rate of organic components in the wood, making the wood color less prone to change, but also stabilizes the gas environment inside the drying chamber 1, reducing the risk of fire and explosion. Finally, the electric heating steam generator 7 is turned on, allowing hot steam to enter the spiral diverter pipe 9 through the steam delivery pipe 8 and be sprayed out into the drying chamber 1 through the nozzle 10. This, combined with the return air chamber 21 at the bottom of the drying chamber 1, connects the output end of the return air duct 22 to an external industrial dehumidifier, achieving the desired wood drying effect. The spiral diverter pipe 9 can cover a larger spray range, allowing the steam to be more evenly distributed within the drying chamber 1. During the drying process, the restoring performance of the powerful spring 5 effectively compensates for the shrinkage stress of the wood as its thickness shrinks, maintaining a compressed state, preventing deformation, and ensuring drying quality. The activation of the low-speed fan 2 promotes micro-circulation of air within the drying chamber 1, balancing temperature and humidity differences in different areas, further ensuring processing quality. Data from multiple temperature and humidity sensors 17 and oxygen sensors 16 installed inside the drying chamber 1, fed back to the PLC control panel 24, allows real-time monitoring of the drying environment quality within the drying chamber 1, providing data support for operator operations and ensuring processing quality.
